Say hello to fully automated GitHub mirrors of every plugin in the
WordPress.org plugin repository. These aren't your typical plugin Git
repositories. These mirrors can be used for fast, efficient, and
automated plugin updates using Composer, and don't require "sync
scripts" or separate Subversion checkouts for plugin development. They
also offer a way for plugin developers to make the move to Git even
while others continue working on the same plugin using Subversion
uninterrupted.
